Stiffness and strength per kilogram
The elastic section modulus Zx governs bending strength. Dividing it by the weight shows how efficiently each size uses its steel: higher is better when weight is the cost driver.
| Section | kg/m | Ix (cm⁴) | Zx (cm³) | Zx per kg/m |
|---|---|---|---|---|
| C6x8.2 | 12.20 | 545 | 71.3 | 5.84 |
| C6x10.5 | 15.60 | 629 | 82.6 | 5.29 |

How the weight is calculated
Mass per metre = cross-sectional area × density of steel = 15.40 cm² × 0.785 kg/(cm²·m) = 12.09 kg/m.
Rolled sections are made to a nominal mass, and the actual mass can differ by a few percent within the tolerances of ASTM A6. For purchasing, invoicing by weight or checking deliveries, use the producer's stated mass.
Typical uses
Channels are used as purlins, girts, stair stringers, trimmers, frames and bracing, and back to back as built-up columns.
